Embodiment 1 of the present invention will be described below with reference to FIGS. FIG. 1 is a diagram illustrating a configuration example of a tablet mark printing machine according to Embodiment 1 of the present invention. FIG. 2 is a diagram illustrating an example of a printing device portion of the tablet mark printing machine according to the first embodiment of the present invention. FIG. 3 is a diagram illustrating an example of a tablet on which a mark is printed according to the first embodiment of the present invention.

As shown in FIG. 1, the tablet mark printing machine 100 according to the first embodiment of the present invention includes a disk 11, a disk 12, a disk 13, a parts feeder 14, a tablet insertion unit 15, a printing device 21, a printing device 31, and an imaging device 41. The imaging device 51, the storage box 17, and the like. The disk 11 is provided with the main surface vertical, the disk 12 is provided vertically so as to be orthogonal to the disk 11 and the side surfaces are close to each other, and the disk 13 is horizontal so as to be orthogonal to the disk 12 and the side surfaces are close to each other. Is provided. The disk 11, the disk 12, and the disk 13 include a plurality of suction holes on the side surface circumference, and the tablets T can be sucked and held in the suction holes.

The tablet in the present invention has a secant on the first surface and no secant on the second surface (see FIG. 3 and the like). The secant is a groove provided on the tablet surface so as to be easily broken when the tablet is divided. As shown in FIG. 3, there are many secant lines in which a single groove is provided in a straight line from one end of the tablet to the other so that it can be divided in half. Some tablets are provided with two grooves so that they can be divided into quarters. Here, in the tablet T, a circumferential surface between the first surface and the second surface which are two main surfaces is referred to as a side surface.

Next, the operation of the tablet mark printing machine 100 will be described. First, the tablet T is loaded from the tablet loading unit 15 into the parts feeder 14. The tablets T put into the parts feeder 14 are gradually aligned in the horizontal direction by the vibration or rotation of the parts feeder 14. The aligned tablets T are adsorbed at the final end of the parts feeder 14 by the adjoining adsorbing holes among the plural adsorbing holes provided on the circumference of the disc 13. The tablet T sucked and held in the suction hole on the side surface circumference of the disk 13 is horizontally rotated so as to approach the disk 12 as the disk 13 rotates counterclockwise. Then, the tablet T that has moved close to the disk 12 starts to be adsorbed to the adsorbing hole adjacent to the disk 12, and the adsorption of the adsorbing hole of the disk 13 is released so that one main surface of the tablet T is placed on the disk 12. It is made to adsorb | suck to the said adsorption hole. The disk 12 rotates in the vertical direction so that the adsorbed and held tablet T comes close to the disk 11 by rotating clockwise. Then, the tablet T that has moved close to the disk 11 starts to be adsorbed to the adjacent adsorption hole in the disk 11, and the adsorption of the adsorption hole in the disk 12 is released, so that the side surface of the tablet T is adsorbed to the disk 11. Adsorb and hold in the hole. The tablet T adsorbed and held on the disk 11 is rotated vertically in the counterclockwise direction as the disk 11 rotates.

Next, the dividing line position recognition and mark printing of the tablet T adsorbed on the disk 11 will be described in detail with reference to FIGS. The disk 11 is received by adsorbing the side surface of the tablet T in an upright posture from the disk 12 at the beginning of the lateral rotation direction, and sucks and holds the tablet T in an upright posture. As the disk 11 rotates counterclockwise, the tablets T held by suction are sequentially rotated counterclockwise. When the tablet T is rotated to a position where the imaging device 41 and the imaging device 51 can image, the tablet T is detected by a sensor (not shown), and one imaging surface of the tablet T is imaged by the imaging device 41. The other main surface of the tablet T is imaged. Both the imaging device 41 and the imaging device 51 are configured by CMOS sensors, and take an image of the rotating tablet T so as not to blur the image using an electronic shutter and a strobe.

Both the imaging device 41 and the imaging device 51 are connected to a control device (not shown). Each image captured by the image capturing device 41 and the image capturing device 51 is subjected to image processing by the control device to determine whether the first surface with the secant line is one main surface or the other main surface, and The position and rotation angle of the secant on the first surface are recognized (referred to as “secant position recognition”). That is, if it is determined that there is a secant on one main surface captured by the imaging device 41, this one main surface is determined as the first surface, and it is determined that there is a secant on the other main surface captured by the image capturing device 51. Then, the other main surface is determined as the first surface. Then, on the surface determined to be the first surface, the position and rotation angle of the secant are recognized (secant position recognition). Recognition of the position of the secant and the rotation angle can be recognized by image processing software. For example, it may be recognized by a template matching method or may be recognized by using a boundary detection method.

In Example 1, the position of the dividing line and the rotation angle are recognized by the dividing line position recognition. However, when the center position of the tablet T is supplied to the imaging device and the printing device so as not to deviate, Only the rotation angle may be recognized without recognizing the secant position.

The tablet T for which the dividing line position has been recognized is rotated and conveyed to a position where the printing device 21 and the printing device 31 can print the mark. Both the printing device 21 and the printing device 31 are configured by an ink jet printer, and print marks having an arbitrary shape by ejecting ink from nozzles. In the first embodiment, the mark M1 is printed by the second surface printing apparatus that faces the second surface that is determined not to have a secant line.

Here, the second surface printing device refers to the printing device 21 or the printing device 31 that performs printing on the second surface of the tablet T, that is, the surface having no secant. For example, in FIG. 1 or FIG. 2, when the front surface, that is, one main surface has a secant line, the printing device 21 becomes the second surface printing device, and the back surface, that is, the other main surface, In the case of having a secant line, the printing device 31 is the second surface printing device.

Both the printing device 21 and the printing device 31 are connected to a control device (not shown). The control device controls the print data that defines the mark shape to be instructed to the printing device that executes printing, either the printing device 21 or the printing device 31, and to execute the printing.

Thus, in Example 1, at least the mark is printed at a position / rotation angle corresponding to the secant position on the second surface. In other words, the position and rotation angle on the second surface where the secant line position recognition and rotation angle on the first surface recognized by the secant line position recognition are reversed (that is, the position corresponding to the secant position on the second surface) are calculated. A linear solid line is printed at a rotation angle as a mark from one end of the tablet to the other end. The printing color of the mark is arbitrary, but the mark can be easily understood by printing with a color different from the tablet surface color. An example in which a straight solid line is printed as a mark M1 on the second surface is shown in FIG.

In Example 1, a straight solid line was printed as the mark M1, but the present invention is not necessarily limited to this, and the mark shape can be appropriately selected depending on the convenience of the tablet. For example, a straight broken line or a dotted line may be printed, or a one-dot chain line may be printed. In addition to the mark M1, characters such as drug names and company names may be printed. Further, the thickness of the mark M1 can be arbitrarily selected, and the mark thickness that can be identified can be selected for convenience of the tablet. The length of the mark M1 can also be arbitrarily selected, and may not be from one end of the tablet to the other end.

The tablet T on which the mark M1 is printed further rotates the disk 11 counterclockwise, and the tablet T is stored in the storage box 17 near the end of the disk 11 in the rotation direction.

In Example 1, the appearance inspection and the print inspection of the tablet T are not performed. However, for the convenience of the tablet T, the appearance inspection of cracks and chips may be performed simultaneously with the dividing line position recognition. Further, a print inspection may be performed after the mark M1 is printed. Furthermore, you may comprise so that the side surface external appearance test | inspection may be carried out by imaging the side surface of the tablet T by which one main surface is adsorb | sucked to the disk 12 with an imaging device.

As described above, in Example 1, there is provided a tablet mark printing method for printing a mark at a divided position of a tablet having a secant on the first surface and no secant on the second surface. A method for visualizing or encapsulating by a tablet mark printing method, comprising performing a dividing line position recognition for recognizing a dividing line position on one surface and printing the mark at a position corresponding to the dividing line position on at least the second surface. In this case, the tablet dividing position can be understood even when viewed from a surface without a dividing line.

A tablet mark printing machine for printing a mark at a tablet dividing position having a dividing line on the first surface and not having a dividing line on the second surface, wherein the dividing line recognizes the dividing line position on the first surface of the tablet. A tablet mark printing machine comprising: a recognition device that performs position recognition; and a second surface printing device that prints the mark at a position corresponding to the secant position on at least the second surface. The dividing position of the tablet can be understood even when viewed from the side without the dividing line in the converting apparatus.

Furthermore, the tablet has a secant on the first surface and no secant on the second surface, and at least a mark is printed at a position corresponding to the secant on the second surface. Thus, in the visual inspection or the packaging apparatus, it is possible to know the tablet dividing position even when viewed from a surface without a dividing line.

The second embodiment of the present invention is different from the first embodiment in that a mark is printed in the secant groove on the first surface in addition to the second surface of the tablet. Hereinafter, Example 2 will be described with reference to FIG. FIG. 4 is a diagram illustrating an example of a tablet on which a mark is printed according to the second embodiment of the present invention.

As in the first embodiment, when the tablet T is rotated by the disk 11 to a position where the imaging device 41 and the imaging device 51 can image, the tablet T is detected by a sensor (not shown), and one of the tablets T is detected by the imaging device 41. The main surface is imaged, and the other main surface of the tablet T is imaged by the imaging device 51. Each image picked up by the image pickup device 41 and the image pickup device 51 is subjected to image processing by a control device (not shown) to determine whether the first surface with the secant line is one main surface or the other main surface. The position and rotation angle of the secant are recognized on the first surface (referred to as “secant position recognition”). That is, if it is determined that there is a secant on one main surface captured by the imaging device 41, this one main surface is determined as the first surface, and it is determined that there is a secant on the other main surface captured by the image capturing device 51. Then, the other main surface is determined as the first surface. Then, on the surface determined to be the first surface, the position and rotation angle of the secant are recognized (secant position recognition).

The tablet T for which the dividing line position has been recognized is rotated and conveyed to a position where the printing device 21 and the printing device 31 can print the mark. Both the printing device 21 and the printing device 31 are configured by an ink jet printer, and print marks having an arbitrary shape by ejecting ink from nozzles. In the second embodiment, in addition to the printing of the mark M1 by the second surface printing device facing the second surface, the first surface printing device facing the first surface having the dividing line causes the straight line in the dividing line groove. A mark M2 composed of a solid line is printed from one end of the tablet to the other end (see FIG. 4).

In Example 2, a straight solid line was printed as the mark M2, but the present invention is not necessarily limited thereto, and the mark shape can be appropriately selected depending on the convenience of the tablet. For example, a straight broken line or a dotted line may be printed, or a one-dot chain line may be printed. In addition to the mark M2, characters such as a medicine name and a company name may be printed. Further, the thickness of the mark M1 can be arbitrarily selected, and the mark thickness that can be identified can be selected for convenience of the tablet. The length of the mark M1 can also be arbitrarily selected, and may not be from one end of the tablet to the other end. Further, the mark M1 on the second surface and the mark M2 on the first surface may be marks having different shapes.

Thus, in Example 2, in addition to the 2nd surface of a tablet, since it comprised so that a mark might be printed in the groove | channel of a dividing line also in the 1st surface, there is a dividing line visually or in a packaging apparatus. The tablet division position can be clearly seen on the surface.

The third embodiment of the present invention is different from the first or second embodiment in that the mark printed on the tablet has a shape in which a division abnormality can be determined after the tablet is divided. The third embodiment will be described below with reference to FIGS. FIG. 5 is a diagram illustrating an example of a tablet on which a mark is printed according to the third embodiment of the present invention. Fig.6 (a) is a figure explaining the example which divided | segmented the tablet on which the mark in Example 3 of this invention was printed normally. FIG. 6B is a diagram illustrating an example in which the tablet on which the mark is printed according to the third embodiment of the present invention is abnormally divided. FIG.6 (c) is a figure explaining another example which abnormally divided the tablet in which the mark in Example 3 of this invention was printed.

That the mark printed on the tablet has a shape that can be determined to be abnormal after dividing the tablet means that it is possible to determine whether the division is normal or abnormal by looking at the mark after dividing the tablet. . FIG. 5 shows an example of a mark having a shape in which a division abnormality can be determined after tablet division. The mark M3 shown in FIG. 5 is an example in which a straight line is printed along the position corresponding to the dividing line on the second surface so as to include both ends of the dividing line in the width direction. The mark M4 is the width direction of the dividing line groove. This is an example in which a straight line is printed along a position corresponding to a secant on the first surface so as to include both ends. The marks M3 and M4 are straight lines printed along positions corresponding to the dividing lines so as to include at least both ends in the width direction of the dividing line grooves.

Here, a straight line printed along the dividing line so as to include positions corresponding to both ends in the width direction of the dividing line groove is, along the dividing line, including both ends in the width direction forming the dividing line groove on the first surface. The printed line may be a straight line including a position slightly outside the groove. In addition, the second surface may be printed on a straight line having a width including both ends in the width direction forming the groove of the dividing line on the first surface at a position / rotation angle corresponding to the dividing line. May be. Furthermore, the straight lines of the mark M3 and the mark M4 in the first embodiment are solid lines, but are not necessarily limited thereto, and may be a broken line, a dotted line, or a one-dot chain line. Further, the mark M3 and the mark M4 may be marks having different shapes.

FIG. 6 shows an example in which the tablet T printed with the marks M3 and M4 shown in FIG. 5 is divided. FIG. 6A shows an example of normal division. That is, in the case of normal division, it can be confirmed that one end in the width direction of the mark M3 or the mark M4 continues without interruption from one end of the tablet T to the other end, and the mark M3 Or the other edge part of the width direction in the mark M4 cannot be confirmed. On the other hand, in the case of abnormal division, it can be confirmed that one end in the width direction of the mark M3 or the mark M4 continues without interruption from one end of the tablet T to the other end, and At least a part of the other end portion in the width direction of the mark M3 or the mark M4 can be confirmed (FIG. 3B). Alternatively, in another example, it is not possible to confirm that one end in the width direction of the mark M3 or the mark M4 continues without interruption from one end of the tablet T to the other end (interrupted in the middle). (FIG. 3C).

That is, one end in the width direction of the mark M3 or the mark M4 continues without interruption from one end of the tablet T to the other end, and the other end in the width direction of the mark M3 or the mark M4. If the condition that the part cannot be confirmed can be confirmed, it can be determined that the division is normal, and if all of the conditions cannot be confirmed, it can be determined that the division is abnormal.

In Example 3, the mark M4 is printed on the first surface and the mark M3 is printed on the second surface. However, the present invention is not limited to this, and the mark M3 is printed only on the second surface without printing the mark on the first surface. It is good also as a structure which prints.

As described above, in the third embodiment, the mark has a shape in which the division abnormality can be determined after the tablet is divided, so that whether the mark is normally divided after the tablet division or the abnormal division is determined visually or in the packaging apparatus. can do.

Example 4 of the present invention is a straight line printed along the dividing line so that the mark includes positions corresponding to both ends in the width direction of the groove of the dividing line, and the number of the straight line is two. Is different. Hereinafter, Example 4 will be described with reference to FIG. FIG. 7 is a diagram illustrating an example of a tablet on which a mark is printed according to the fourth embodiment of the present invention.

In Example 4, as shown in FIG. 7, the mark M5 on the second surface of the tablet T has a straight line corresponding to the dividing line so as to include both ends in the width direction forming the groove of the dividing line on the first surface. A straight line printed from one end of the tablet T to the other end at the rotation angle, and the straight line at a position corresponding to the one end in the width direction of the groove and the other end Are two of the other straight lines at positions corresponding to. Further, the mark M6 on the first surface is a straight line printed along the dividing line so as to include the widthwise end part forming the dividing line groove, and the straight line corresponds to one end part in the groove width direction. There are two lines, one straight line at the position and the other straight line at the position corresponding to the other end. That is, no mark is printed at a position corresponding to the central portion in the groove width direction.

Here, the mark M5 or the mark M6 may be a straight line, and may be a broken line, a dotted line, or an alternate long and short dash line. Further, in Example 4, the mark M6 is printed on the first surface and the mark M5 is printed on the second surface, but the present invention is not limited to this, and the mark is not printed on the first surface, and only the second surface is marked. 5 may be printed. Further, the mark M6 and the mark M5 may have different shapes.

The mark M5 or the mark M6 in the fourth embodiment also has a shape in which a division abnormality can be determined after tablet division. That is, in the case of normal division, it can be confirmed that one end in the width direction of the mark M5 or the mark M6 continues from one end to the other end of the tablet T without interruption, and the mark M5 Or the other end of the mark M6 in the width direction cannot be confirmed. In the case of abnormal division, it can be confirmed that one end in the width direction of the mark M5 or the mark M6 continues from one end of the tablet T to the other end without interruption, and the mark M5 Or at least one part of the other edge part of the width direction in mark M6 can be confirmed. Alternatively, in another example, it cannot be confirmed that one end in the width direction of the mark M5 or the mark M6 continues without interruption from one end of the tablet T to the other end (interruption occurs in the middle). )

That is, one end in the width direction of the mark M5 or the mark M6 continues without interruption from one end of the tablet T to the other end, and the other end in the width direction of the mark M5 or the mark M6 If the condition that it cannot be confirmed can be confirmed, it can be determined that the division is normal, and if all of the conditions cannot be confirmed, it can be determined that the division is abnormal.

Thus, in Example 4, the mark is a straight line printed along the dividing line so as to include positions corresponding to both ends of the dividing line in the width direction, and the straight line is one of the grooves in the width direction. Since there are two straight lines, one straight line at a position corresponding to the end and the other straight line at a position corresponding to the other end, the center portion in the groove direction does not print a mark, so that the amount of ink can be saved. At the same time, since the mark has such a shape that it is possible to determine the abnormal division after the tablet is divided, it is possible to determine whether the division is normal or abnormal after the tablet is divided by the visual inspection or the packaging apparatus.

The tablet mark printing method, tablet mark printing machine, and tablet according to the present invention can be widely applied to fields where tablets need to be divided.
